AUGUST R. LEWIS, OF KENT, WASHINGTON.

BROODER.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed September 4, 1907. Serial No. 391,310.

To all whom it may concern:

Be it known that I, AUGUST It. Lrzwis, a citizen of the United States,residing at Kent, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Broeders, of which thefollowing` is a specification, reference being had therein to theaccompanying drawings.

This invention relates to broeders; and its object is the provision of adevice Which will be of inexpensive and durable construction, which maybe readily adjusted to accommodate young chickens of various sizes, andwhich will require but little attention on the part of the operator.

lith the foregoing ends in view the invention consists in the novelconstruction, adaptation and combination of parts as will be hereinafterdescribed and claimed.

In the drawings, Figure 1 is a side elevation of a broeder embodying myinvention; Fig. 2 is a longitudinal vertical section of the same, butwith the hinged cover portion of the casing and the doors shown in anopen condition; and Fig. 3 is a cross sectional view taken through 3 3of Fig. 1.

The broeder proper is comprised of a casing, or box, having a bottom 5,sides 6, a front end 7, a back end 8 and a to 9. In the front end is anopening 7 provi ed with a hinged door 7". Said top is formed with anopening adjacent to each of its ends whereby access may be had to theinterior of the casing and are provided With closures which are hingedto a transverse bar-.member 9 of the top. The closure for the opening10, which is adjacent to the back end of the casing, is made of twoparts 11 and 12, of which the rearmost one is the smaller and isprovided with a pane of glass 12. The closure 13 for the other openingis also provided With a glass pane 13 Which is considerably larger thanthe pane of the closure 12 in order to admit the li ht to a greaterdegree toward the head en of the apparatus.

Within the casing is a Hoor 14 adapted to be adjustably sup orted atvarious heights and which may be conveniently done by props 15 which arehinged to the casing-bottom and have their free ends tiltably raised orlowered by lines 16 which are attached thereto and about a rotatable rod17, as illustrated in Figs. 2 and 3. This rod is journaled in the sidemembers of the casing and has an enlarged extremity 17 protrudingoutwardly from one of such sides and whereby the turning of the rod iseffected. This extremity is provided with peripheral notches 17 forengagement with a pawlbolt 18 for securing the rod against rotation andthus maintain the floor, which is supported upon the props, at anyadjusted height.

Just below the casing top are transverse poles 19 and 2() which arerespectively disposed to be in proximity of the door 7 and below the topbar-member 9', and have ends, such as 20, extended outside of the casingfor turning the same in order to raise or lower the curtains 19 and 20which are rolled about the respective poles. Positioned within the casinand immediately below the closure part 11 1s a tank 21 formed withstraight side Walls 22, a fiat cover-plate 23, desirably of metal, and acurved bottom 24, formed of a flexible sheet of rubber or equivalentmaterial.

25 is a boiler of any appropriate size or shape, but preferably of thetype illustrated and comprising an outer cylindrical shell 26 and aninner truncoidal shell 26 arran ed concentric with each other and afforing therebetween a space 27 for the heating water which is suppliedthrough an opening 26 having a cap 28.

A pipe 29 makes communication between the top of the boiler water-spaceand the top of the tank and similar connection is made between thebottoms of these elements by a pipe 30, and by such an arrangement acirculation of water is created in the heating system, as indicated bydarts in Fig. 3, when heat is generated by the boiler. The pipes inpassing through the casing are supported thereby and in turn sustain theboiler and, ordinarly, the tank by rigidly connecting the adjacent sidewall of the latter with the pipes and extending one of the pipes, as 29,to be socketed within a recess 22 1n the remote wall. Pipe 29, adjacentits outer end is formed on its top with an opening 29', by means ofwhich the Water passing through pipe 29, from the boiler escapes intothe tank.

In broeders of uncommonly large size, resort may be had to suitablesupports supplementary to the pipes, as above explained; however, it isadvantageous to extend one of the pipes as shown in order that theintake and delivery of the water will occur at opposite sides of thetank and cause a cross current therein. The water is heated by asuitable heat generator, such as a lamp 3l having its chimney extendedinto the chamber 32 of the boiler and from this chamber the smoke orother con'ibustion gases are led away by a tubular conduit extending towithin a short distance of the front end of the casing and thencethrough and terminating beyond the further side of the latter'.

There the conduit enters the casing an annular space is provided,indicated by 34 in Fig. 1, to furnish a delivery passage for a hot-airtube 35 which surrounds the conduit and reaching from within a shortdistance of the boiler to its entry to the casing provides thereby aduct for a supply of heated air to the brooder. The smoke conduitimparts heat to the current of air entering said duct and which is ampleto maintain the compartment intermediate curtains 19' and 20 at asuitable temperature. Vent holes 36 are provided in the back end of thecasing to allow of the escape of the foul gases emanating from thebrooder-occupants.

37 represents an under cover of wool or leecy fabric for the tank bottomto protect the young poultry from coming in direct contact with therelatively hot tank and presenting a comfortable surface to nestleagainst.

In operation, the boiler is first filled, through the opening QG", withwater at a boiling temperature, the lamp is then lighted and all of thecasing closures shut. Then the brooder becomes heated to a suitabletemperature, the chickens are introduced by raising the hinged part 12.Should the floor be found to be improperly adjusted to accommodate thechickens, it may be raised or lowered, as desired, by manipulating therod 17.

It is found that extremely young broods will, as a rule, remain withinthe compartment to the rear of the curtain 20 and may be inspectedthrough the glazed closure 12. As the chickens grow, they will pass intothe cooler and better lighted compartment at the other side of thiscurtain and thence, when the external temperature permits, through theopening 7 to the outside. The temperature within the brooder iscontrolled throughV regulating the lamp and also the openin of the door7 and the closures in the casing top.

The invention is well adapted for the pur poses for which designed,requiring but little attention, and its action is not subject to rapidchanges in the surrounding temperature. The interior of the brooder isaccessiv ble for cleaning and its occupants are at all times capable ofbeing inspected.

What I claim is,-

1. In a broeder, the combination of a tank positioned interiorly of thebrooder-casing, a boiler' positioned outside of the casing, pipeconnections between the upper and lower' portions of the tank withcorresjiionding parts of the boiler, a lamp for generating heat Withinthe boiler, a conduit leading from said lamp through the casing, and atube surrounding said conduit and spaced therefrom having one endextending in the casing and the other end open to th 1 atmosphere.
